An approach to modeling induction period in crystallization fouling

In this study the fouling of calcium carbonate CaCO₃ and calcium sulfate dehydrate CaSO₄·2H₂O each from single salt solutions on stainless steel surfaces as well as modified surfaces was investigated. Based on experimental investigations a mathematical model for estimation of the induction time was developed. The model was integrated in a software code, computed and compared with experimental data. As a criterion for the induction period the corresponding ratio of Biot numbers was applied.
